A paramagnetic chiral smectic C material has been studied by electron paramagnetic resonance (EPR) for the first time. EPR, in conjunction with differential scanning calorimetry and optical microscopy, provides information about the molecular arrangements in the different phases. The spectra of a chiral smectic C liquid crystal copper(II) complex derived from a chiral Schiff base are discussed, which reveal polymorphic transformations that may be related to the asymmetry of the chiral molecules.
